<p>
Verify's a certificate chain after looking up and adding any missing
certificates to the chain.
</p>
<p>
<em class="parameter"><code>chain</code></em> is a chain of <a class="link" href="GTlsCertificate.html" title="GTlsCertificate"><span class="type">GTlsCertificate</span></a> objects each pointing to the next
certificate in the chain by its <code class="literal">issuer</code> property. The chain may initially
consist of one or more certificates. After the verification process is
complete, <em class="parameter"><code>chain</code></em> may be modified by adding missing certificates, or removing
extra certificates. If a certificate anchor was found, then it is added to
the <em class="parameter"><code>chain</code></em>.
</p>
<p>
<em class="parameter"><code>purpose</code></em> describes the purpose (or usage) for which the certificate
is being used. Typically <em class="parameter"><code>purpose</code></em> will be set to <a class="link" href="GTlsDatabase.html#G-TLS-DATABASE-PURPOSE-AUTHENTICATE-SERVER:CAPS" title="G_TLS_DATABASE_PURPOSE_AUTHENTICATE_SERVER"><span class="type">G_TLS_DATABASE_PURPOSE_AUTHENTICATE_SERVER</span></a>
which means that the certificate is being used to authenticate a server
(and we are acting as the client).
</p>
<p>
The <em class="parameter"><code>identity</code></em> is used to check for pinned certificates (trust exceptions)
in the database. These will override the normal verification process on a
host by host basis.
</p>
<p>
Currently there are no <em class="parameter"><code>flags</code></em>, and <a class="link" href="GTlsDatabase.html#G-TLS-DATABASE-VERIFY-NONE:CAPS"><code class="literal">G_TLS_DATABASE_VERIFY_NONE</code></a> should be
used.
</p>
<p>
This function can block, use <a class="link" href="GTlsDatabase.html#g-tls-database-verify-chain-async" title="g_tls_database_verify_chain_async ()"><code class="function">g_tls_database_verify_chain_async()</code></a> to perform
